FUMIGATOR.

Speccation of Letters Patent.

Patented Dec. 16, 1919.

Application led May 1, 1919. Serial No. 293,902.

To all whom t may concern:

Be it known that I, CHARLES F. Hoon, residing at Connellsville, in thecounty of Fayette and State of Pennsylvania, a citizen of the UnitedStates, have invented or discovered certain new and useful Improvementsin Fumigators, of which improvements the following is a specification.

The object of the invention is to provide a fumigator of simple andconvenient construction and one which may be used safely.

The accompanying drawing is a vertical central sectional view of anembodiment of the invention.

In the practice of the invention there is provided a vessel having wallswhich divide it into two closed compartments adjacent to each other.Each of the two compartments contains one of two substances which whenmixed with each other combine to form a disinfectant gas such as formicacid gas, and means are provided whereby the contents of the twocompartments may be readily intermingled.

While various forms of vessels may be used, the two compartments arepreferably formed, as illustrated in the drawing, by placing a container1 within an outer and larger container 2. The outer container ispreferably provided with an opening 3 adapted to be closed by a suitablecap 4. The wall 6 of the inner container adjacent to the opening 3 ispreferably formed of glass or other material which may be readily brokenby striking it with a convenient article, such as a screw driverinserted through the opening 3 after the removal of the closure or cap4. If desired the adjacently disposed walls of the two containers may beseparated by a suitable packing 5.

The two compartments, thus or otherwise formed, are preferably filled,the inner with from the outer container and the glass wall 6 broken, asby means of a screw driver inserted through the opening 3. rllheformaldehyde solution then flows into the compartment formed by theinner container l and mixes with the potassium permanganate whichoxidizes the formaldehyle, generating formic acid gas. The reaction isexothermic, effecting a temperature rise of approximately 100O F. Theheat thus produced volatilizes the essential oil of perfume which leavesin a room an agreeable odor for an extended period.

In using a fumigator constructed according to the invention, there iseliminated the usual danger of fire incident to the use of fumigatorswherein formaldehyde is oxidized by heating it with a flame.

I claim as my invention:

A fumigator including in its structure two compartments separated` by afragile partition wall, the said partition wall being accessible fordisruption.

In testimony whereof I have hereunto set my hand.
